The instantaneous centre of a member lies at the point of intersection of two lines drawn at the ends of the member such that the lines are inclined to the direction of motion of the ends at
The magnitude of the kinetic friction bears a constant ratio to the normal reaction between two surfaces. The ratio being slightly less than that in the case of limiting friction
All of these
For moderate speeds the force of friction remains constant but decreases slightly with the increase of speed
The force of friction always acts in a direction opposite to that in which a body is moving
